Hi
I was running RePlACe for designs which we had uploaded. This time I am getting Segmentation fault. I did quick valgrind and below is what I get. Anything missing?

Hi
You can use below testcase:
testcase.tar.gz
Use the below command:
valgrind RePlAce -bmflag etc -lef /usr/local/share/qflow/tech/osu018/osu018_stdcells.lef -def layout/map9v3.def -output replace_output
Thanks
Kunal
Hi Kunal,
Your DEF don't have ROW definition, so it's not possible to generate a placement solution.
I'll generate an error for this.
Thanks Mingyu. Got it...
Do you have any script that would generate crude floorplan def (with the right syntax) from synthesized netlist? If yes, can you please share?
We're building that program now. (called Verilog to DEF translator/generator). This generator is required to execute both of floorplanner and placer. It'll be open-sourced soon.
Sounds good
Thanks Mingyu
Welcome.
